BLANK OR UNIT FOR MAKING DENTAL PLATE 2 Claims.

My invention relates to improvements in blank or unit for making adental plate, which in dentistry is the mounting or denture whichcarries the teeth.

5 One object of my invention is the provision of a blank or unit formaking or produc ng a dental plate which will be made of a suitablematerial having the exterior appearance of the healthy gum to provide anattractive and beautiful plate or mounting for the teeth.

Another object of my invention is the provision of a blank or unit formaking or producing a dental plate or mounting which under the necessarypressure and heat will become soft or pliable and conform to and becomethe substitute of the Wax pattern or impression and receive the teeth toproduce a most satisfactory mounting and present a very attractiveexterior appearance.

Another object of my invention is the provision of a blank or unit formaking or producing a dental plate which will be shaped toconform to thegeneral fit of the mold and take the place or become the substitute ofthe original wax impression or pattern as to the location of the teethand also the roof of the mouth in order to produce a perfectly fittingdenture.

Another object of my invention is the production of a blank or unit formaking or producing a plate which will meet every requisite of such anarticle in a most practical and efiicient manner and which may beproduced at the proper price to fill the demand for such a denture.

With these objects in view my invention consists of blank or unit formaking or producing a dental plate or mounting embodying novel featuresof construction and arrangement of its parts, substantially as describedand claimed and as shown in the accompanying drawing, in which:

Figure 1 represents a perspective view of the blank or unit for makingthe dental plate or mounting constructed in accordance with andembodying my invention.

Figure 2 represents a longitudinal sectional view of the blank or unitfor producing the plate or mounting, and

Figure 3 represents a transverse sectional view taken at a right angleto Figure 2.

The blank or unit A which produces the plate or mounting, is of thedesired size and is made of a suitable material to have the exteriorappearance of the healthy gum, and in general outline the plate is ofrectangular form with flat upper and lower faces and, having the pair ofbevelled edges B, the bevelled angular corners C,

and the bevelled straight edge D, while from the edge opposite saidstraight edge 13, the face or" the plate is formed with the recess E.

In the manufacture of the dental plate from my blank or unit, the waxpattern or impression is placed between the mold sections and theinvestment material is allowed to harden to form the mold sections. Themold is then subjected to heat to remove the Wax, and the blank or unitis then placed upon the section of the mold containing the teeth, andthe mold with the blank or unit is placed in a vulcanizer or heaterunder the influence of a press, and said blank or unit in its properrelation is subjected to the pressure exerted by the press and in thepresence of the necessary degree of heat the blank or unit becomes softand the bevelled edges position with ease to receive the teeth While therecess by reason of thinning the wall of the plate produces a perfectfit to the roof of the mouth-and thus the construction of the plateproduces a perfect plate or mounting for the teeth. It will thus benoted that the blank or unit is adapted to become the substitute for theWax pattern or impression and when removed from the mold a perfectdenture or plate is produced. The blank or unit is made of any of thesuitable materials used for making dental plates, such as hard rubber,or like material, which is colored to resemble the healthy gum.

I have found from many years experience as a manufacturer of dentalplates that this blank or unit produces a plate which is highlyefiicient and practical and persons skilled in the construction ofdental plates will readily understand and appreciate the advantages ofmy improvements.

I claim:

1. As a new article of manufacture, a blank or unit for making a dentalplate having upper and lower flat faces and a surrounding bevelled edgeand having a recess extending inwardly from one edge.

2. As a new article of manufacture, a blank or unit for making a dentalplate, having a surrounding bevelled edge, having two of its cornersangled or cut away and having a recess extending inwardly from one ofits edges.
